Spam is here to stay. And whether you like it or not, you have to face spam squarely and do your share in mitigating its negative effects. Although spam can be a source of information, spam is taken negatively because it is unsolicited. Who would ever want to receive bulk of emails containing product advertisements and easy get -rich-schemes information? Spam can slow down your server's bandwidth and can be a form of spy ware designed to steal confidential information from your computer.
